Changing the charge fuse
The charge fuse is on the underside of the
chassis, over the right rear wheel, next to the
circuit breaker, see fig. 49. Switch off the main
power breaker and the charger, if in use, before
you change the charge fuse.
NB! The circuit breaker must be in the “ON” position
during charging.
Changing the seat/lights fuse
There are two fuses in the SLS drive stage,
F1 (24V unswitched) and F2 (24V switched).
These protect two outlets, located to the left of the
SLS drive stage, next to the charge socket. One of
the outlets (24V unswitched) supplies power
irrespective of whether the chair is switched on or
off. The other outlet (24V switched) supplies power
only when the chair is switched on. The seat and
lights are normally connected to this outlet.
